The generalized Poincaré conjecture is true topologically, but false smoothly in most dimensions. In fact, for odd dimensions, the smooth Poincaré conjecture is only true in dimensions 1, 3, 5 and 61. In even dimensions it is known that the smooth Poincaré conjecture is true in dimensions 2, 6, 12 and 56.
The full generalization rule allows for hypotheses to the left of the turnstile, but with restrictions.Assume is a set of formulas, a formula, and () has been derived. The generalization rule states that () can be derived if is not mentioned in and does not occur in .
Prolog implementations usually omit the occurs check for reasons of efficiency, which can lead to circular data structures and looping. By not performing the occurs check, the worst case complexity of unifying a term with term is reduced in many cases from (() + ()) to (((), ())); in the particular, frequent case of variable-term unifications, runtime shrinks to ().

In predicate logic, existential generalization [1] [2] (also known as existential introduction, ∃I) is a valid rule of inference that allows one to move from a specific statement, or one instance, to a quantified generalized statement, or existential proposition.
Numeric literals in Python are of the normal sort, e.g. 0, -1, 3.4, 3.5e-8. Python has arbitrary-length integers and automatically increases their storage size as necessary. Prior to Python 3, there were two kinds of integral numbers: traditional fixed size integers and "long" integers of arbitrary size.
[3] The Bonferroni correction compensates for that increase by testing each individual hypothesis at a significance level of α / m {\displaystyle \alpha /m} , where α {\displaystyle \alpha } is the desired overall alpha level and m {\displaystyle m} is the number of hypotheses. [ 4 ]
In generative linguistics, Burzio's generalization is the observation that a verb can assign a theta role (a title used to describe the relationship between the noun phrase and the predicate, such as agent, theme, and goal) to its subject position if and only if it can assign an accusative case to its object. Accordingly, if a verb does not ...
